POST-CAP.

SPECIFICATION forming part of Letters Patent No..734,192, dated July 21;1903.

. Application filed May 11, 1903. Serial No. 156.502. (N model.)

To all whom; it may concern.-

Be it known that I, ALFRED RANDOLPH, a citizen of the United States,residing at Salem, Columbiana county, Ohio, have invented certain newand useful Improvement-s in Post- Oaps, of which the following is aspecifica tion.

This invention pertains to improvements in post-caps employed inbuilding construction in forming the junctures between posts andhorizontal timbers; and the invention will be readily understood fromthe following description, taken in connection with the accompanyingdrawings, in which Figure l is a perspective view of my improvedpost-cap in position of use; Fig. 2, a perspective view of the same whenturned upside down to expose the construction underneath; Fig. 3, aperspective view of the cap in conjunction with posts and girders;

- and Fig. 4,3. perspective view generally similar to Fig. 1,butexhibiting the structure modified for employment with four-way girders.

In the drawings, ignoring Fig. 4 except where specifically referred to,1 indicates a trough-shaped channel formed of plate metal and adapted toreceive the intermediate portion of a girder, or, as will generally bethe case, the contiguous ends of two girders in a common line; 2, thefloor-of the trough; 3, the side walls of the trough; .4, cross-ribs secured upon the floor of the'trough and forming a satisfactory means fordoweling the ends of girders to the trough, so as to prevent theirendwise displacement therein, these cross-ribs to fit into gains in thelower surface of the girders in an obvious manner; 5, a subfloor securedunder the floor 2, transversely of it, and projecting outward to oneside thereof; 6, that portion of the subfloor 5 underlying the floor 2of the trough; 7, rivets or analogous fastenings securing the two floorstogether, the floor of the trough 1 thus having a double thickness atits central portion; 8, downwardly-projectingflanges of the subfloor 5,the same being at right angles to the side walls 3 of the upper trough,these flanges projecting endwise the full length of the subfloor 5; 9,angle -brackets secured against the outer face of one of the side walls3 of the trough and projecting outwardly therefrom and secured rigidlyto the outwardly-projecting portions of flanges 8, theoutwardly-projecting portions of said floor 5 in conjunction with theoutwardly projecting portions of brackets9 forminga half-trough at theside of trough'l, this half-trough being adapted to receive the end of agirder disposed at right angles to the girder or girders disposed in thetrough 1; 10, a cross-rib secured on the outwardly-projecting portion ofsubfloor 5 to engage again in the girder resting thereon and dowel it tothe cap structure; 11, a pair of dependent flanges secured under thesubfloor 5 at right angles to the flanges 8 and at such distance apartas to suit the dimension of the post on which the cap is to rest, theconstruction being in most cases such that the distance between theflanges 11 is about the same as the distance between the side walls 3 ofthe trough; 12, (see Fig. 4,) a second side structure adapting thedevice for a four-way girder construction, this second side structurefor the reception of the fourth girder end being substantially the sameas that heretofore described for the third girder end and being formedby an extension of the subfloor 5 to the second as well as the firstside of the trough 1, flanges 8 being correspondingly prolonged. and asecond set of angle brackets 9 being provided; 13, the main-line girderswith their ends resting'in the trough 1; 1a, the lower post, on whichthe cap rests, the central portion 6 of the subfloor resting on top ofthe post, while the flanges 8 and .11 engage its sides; 15, the upperpost with its foot setting in the trough 1 between the contiguous endsof the girders 13 and also between the side walls 3 of the trough; 16,the third girder with its end resting on the projecting portion of thesubfloor 5 and between the angle-brackets 9, its end" abutting partlyagainst the side wall of the trough and partly against the side of upperpost 15; 17,- holes in the flanges 8, which may be employed inconnection with bolts for securing the cap to the lower post, and 18similar holes in the side walls 3 of the trough, which may be employedin connection with bolts in securing the trough to the upper post.

For four-way girder-work the structure shown in Fig. 4 would beemployed, and in such case the fourth girder would project beyond theposts and in line with the third girder 1G.

I claim as my invention- In a post-cap, the combination, substantiallyas set forth, of a trough formed with a floor and side walls, a subfioorsecured underneath the floor of the trough and projecting beyond theside of the trough, flanges projecting downwardlyfroin the trough-floorand subfioor and extending outwardly under the sidewise-projectingportion of the subfloor,downwardly-projectingflanges disposed betweenand at right angles to the first-mentioned flanges, and angle-bracketssecured to l the outer surface of the trough and to the outwardlyprojecting portion of said subfioor.

ALFRED RANDOLPH.
